DOOR-JAMB SETTER.

Application filed. August This invention relates to devices for settlng door jambs and has for its primary object to provide such a device for accurately setting jambs of doors or similar frames of a building which device will plumb, square and hold both j arnbs perfectly straight and true, rendering it possible to set frames in one half of the time normally required.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a front elevation of a door jamb setter constructed in accordance with this invention, shown applied, and

Figure 2 is a top plan view of the device detached.

In the embodiment illustrated a door jamb is shown comprising side rails or stiles 1 and 2 which are connected by a head rail not shown. The setter constituting this invention is designed to set the door jamb so that the side rails 1 and 2 will be precisely perpendicular with respect to the fioor line 3 of the building.

The device shown constituting the invention comprises a pair of side members or bars 11 and 12 of the same length shown in Figure 1 said members being provided with spirit levels, the air bubbles of which are shown at 13. These bars also have hand grips formed by longitudinal slots 14 so that the device may be easily manipulated.

A toggle joint construction connects the bars 11 and 12 and comprises a rod 15 having its ends oppositely threaded and operating in correspondingly threaded sleeves or castings 16 and 17 sothat when the rod is turned these castings will be moved away from or toward each other according to the direction in which the rod is rotated.

A hand wheel 18 is secured to the rod preferably mid-way its length for actuating it. Two links 19 and 20 are pivotally connected at one end with oppositely disposed lugs 21 as those 19 and 20. Those links 25 and 261- are pivotally connected at their inner end with ears 27 and 28 arranged at diametrically opposite points on the casting or sleeve 17.

In the use of this setter 10* the bars 11 and 12 thereof are arranged between the side members or stiles 1 and 2 of the door jamb as shown in Fig. 1 and turning of the rod 16 by means of the hand wheel 18 will cause said bars 11 and 12 to move away from each other and be held in parallelism. These bars 11 and 12 being engaged with the side bars 1 and 2 of the jamb-will operate to'pumb, square and hold said jambmembers perfectly straight and true so that when they have been so arranged they may be secured by the head member not shown and thus held in proper position. The spirit levels shown at 13 indicate when the frame is level.

This toggle-like structure is simple, strong and durable and may be actuated with great rapidity to set door frames.

We claim In a device of the character described, vertical side bars, links pivotally connected with the side bars, and arranged in pairs adjacent to the ends of the side bars, castings having threaded openings, said links having pivotal connection with the castings, a threaded rod adapted to pass through the threaded openings of the castings, and a hand wheel secured to the threaded rod at a point intermediate the ends thereof for moving the castings towards and away from each other to operate the links.

In testimony that we claim the foregoing as our own, we have hereto afiixed our signatures.
